Hi, I have an ibook G4. Something happened that changed some setting, now whenever I try to download something, or open an email attachment, or drag something from the desktop to the trash, a message pops up that says I can't do it because I have "insufficient privileges". Also, when I go to do something with files (trash them, whatever) a box with a locked padlock symbol comes up and it says "Finder Requires that you type your Password". I type my password and that's when the "insufficient permission" deal comes up. I believe that unlike PC, I think, on Macs an administrator has the same kind of power/privileges as a normal user so Im just stuck. Is there a way around this problem or do I have to put in the disks and just totally erase and re-install OSX? Im a student and this is obviously for school so Id like to do as much without having to resort to reinstalling the whole deal. Any and all help is much appreciated. Thanks.
